The present report deals with the measurement of indicator diagram in combustion chamber of engine in order to obtain the best injection timing and pressure, and the measurement of characteristics of lubricating oil after operation for 160 hours under the rated horsepower (3.5/2000rpm).
The results were obtained as follows;
1. By the change of injection timing and pressure, abnormal maximum combustion pressure for the case of using light oil were observed more often than the case of using rape-seed oil.
2. Ignition timing lag in combustion of fuel trended to be more influenced by the change of ignition timing than the difference of fuels.
3. In the case of ignition timing at 14°CA B. T. D. C., ignition pressure was at 90kg/cm2 and under heavy load, the engine performance of using light oil was lower than the case of using rape-seed oil.
The engine performance using rape-seed oil was better than or equal to the case of using light oil from the discussion of indicator diagram and characteristics of lubricating oil. It was anticipated that the rape-seed oil could be put into practice for fuel for diesel engine.
